How to find out if your unit has the RK3188 or the RK3066?

I was wondering if there was a way you could check the unit if it has RK3188 or RK3066, as there are different places selling different version of these Joying Unit. Also how about the resolution since there is 2 type is there a way to find out what resolution the unit is.

You can check the specs before you buy the unit, as everyone does, right?

Great advice , but I have seen a lot of people getting the wrong unit from sellers so just wanted to double check after I get one...

I thought people were saying some resellers were lying about the specs?

This and some of the unit models are named very similar.

Well, sorry if i seemed not friendly. You should check first of all where to buy, then, check if the seller has good ratings, reviews, etc. Then just double check you can choose between the different specs to the one u want, and ask the seller before buying it just in case. I got mine through aliexpress and didnt have a problem at all. Well, ive bought like 100 times there and never had an issue. Hope this helps a bit more.

I'm looking at getting a system right now that is specifically built my car, Erisin says they have a 5.1 system available now, they seem to have a pretty good rep, so I am interested. Reading here, it seems people are saying 5.1 won't be out till the octa cores are released, so that makes me pause as this is a quad core

rk3066 or rk3188 SOM/MCU board for sale anywhere?

Does anyone know where I can get a replacement SOM/MCU board? Only one I found (RK3188) was on aliexpress for $120. That seems like way too much when the whole device was only $320.
I would prefer a RK3188, but a replacement RK3066 would be appreciated too.

Guys I have already purchased the newer Xtrons one with android 6 and newer 64 proces

Hi,
I have already purchased the newer xtrons android 6 with 2gig mem and newer proces one!!
the reason that I have purchased the newer xtrons hu again is very simpl;
xtrons said to me (via email) that I could send / I may return the old android 5.1 one back and I got what I paid for back, so that was a super super cheapst deal, no other company wanting to do that yet because mine xrtons hu is or was over 4 months old!!!,
so I had to pay only +/- 100 euro for everything.. that's incl. sending the old hu one and receiving (shipping) of the newer xtrons hu one plus 60 euro for the more expensive of the newer xtrons android 6 one, so the totally payment is 100 euros = super super cheapst deal ofcourse !!
Why do I have chosen an xtrons hu again?
1- the offer was "extremly cheap" and it's cost me almost nothings for what I gonna get back: a super brand newer hu one with the most newer components likes newer proces and newer and more ram and more rom onboard and with the most newer software for only 60 euro more.. come on mate is that not a very very very cheap deal or not!?!
2- xtrons is the only hu which it fits 100% without any problems into my Audi!
3- the price + quality + options like dvd player + canbus of the xtrons hu is very very good to mention compare with other companies!
4- The support has become much better after having sent enough emails and explained!
5- the only small issue I have had with the old xtrons hu one was the one way canbus radio station info on my car lcd, the canbus it is not decent made in terms of software and options but not hardware from the company who sold it to xtrons, it is a one click system one and that was it, so the reprograming of the swc button is not possible because it's a cheap made driver was the problem, so all of those emails was for that reason, but nothing else!
6- I found it a very nice look and especially very good working hu for or with my Audi car.. and that is very important!
7- for this very good price + quality + options there is no compatition at the moment for xtrons so that's why I purchased again.
Do I working for xtrons company? huhuhu .. absolutely not, otherwise I don't need to pay 400 euro for buying it.. right !?!
I just wanted to share this cheapst deal ever with you guys

Madyen said:
Hi,
(((excuse me)))
I have not previously responded to your "review" between these 2 hu because I felt it unfair to compare them both like the way you already did.. is not an honestly comparing -and maybe you knew it?- mate!!
Prove it.. you gonna or I hear you say.. right?
Ok here we go..
How it is possible in the Xtrons name that you compare both hu while you did not even have updated your old 5.1 hu at all?
Your 5.1 hu with an very old fw and mcu version while the newer 6.1 hu one is with the most newer fw and mcu come? now is that comparing you called fair
I don't know why you did it that? But maybe.. I may have my own thought of kind of conspiracy but I will keep it for myself and I don't tell it ofcourse
If you are really wanted to comparing both of them honestly then you should first of all update your old hu one first and then compare it with the newer one.. right?

LOL, OK, I rest my case.

Hi,
I'm not allowed as a free man to speak/reply on this forum, I received warning after warning from the mod, otherwise I will learn thing how to keep it burning.. believe it
This is just a super good deal and I wanted to share with the good guys on this forum.. never with thing!!, maybe they can contact them car shop or dealers and asking for an exchange deal like this one?
some may well be very jealous (= thing!) of such a super deal, but that's their business care not mine!
My answer:
First: I'm not as thing called me overly protective!
Second: thing speak with We.. while must speak with I.. because We means alot of people.. believe me!!
Just another boring thing nothing more!
Third: its not an review or test its a super good deal.. nothing more nothing less.. reading is very difficult especially for some thing.. I already knew that!!
Keep it burning !:good:!

Hi,
The big boy is already arrived, am extremely happy with it, compared with the old 5.1 one the difference is between heaven and earth, really is worth every penny I payed for.. literally every penny is worth it, what a nice and decent device and the new ui is wow..
The new firmware is much better then the old one (but it have some childhood disease) so it needs some improvement, Radio + BT.. lost them saved or connection things, is not a big deal but still needs a better firmware, ofcouse for a brand new hu schould men give it some times!
Its fast and clean and ofcourse a beautiful car head unit.
As I already said, i'm extremly happy with the new xtrons hu one, especially with such an cheapest deal ever: + €60 !
Unfortunately, it comes with the same -old- canbus so no newer firmware update!
Ps: indeed, the Radio sound and receive is much better now compared with the old one = new chips!?!
Some Pictures :good:

=================================================================
To the 3 things, thanks given.. Keep it burning mate.. but beware of your seat.. don't let it burning with it !!!!!

Mate (pm) ,
This was not an upgrade hu but a returnable head unit -super- deal, you've already read it as you say?.. you should contact your dealer / reseller and ask him/her kindly for an exchange with the newer one and that you are not satisfied with -the 5.1 one- it, he schould exchange it for you.. that is your right!:good:!
Especially since you bought it only -1M- ago within the exchange warranty period.. so just keep hammering mate.. If he/she a real good dealer -?- is, he/she gonna exchange it for you just like the very kind lady from xtrons did it / arrange it for me!:angel:!
I speak via email with a wonderful and really lovely lady and she is the one who's making this -super- deal happens, I really "love" that lovely (N) lady.. very kind lady from xtrons company!!
I don't have permission from her to mention her name (N) in the forum!
Ps: say to the shop where you bought from (or Ebay) I will pay the difference of the newer one ofcourse!
I wish you many success mate :fingers-crossed:
Edit:
Otherwise, just ask your money back and then you can buy the newer one!
Again it is your right within the one month period!

Hey @Madyen, I was wondering if you could post the .APK for the Vehicle Information app that includes data on fuel use and tire pressure from your new Xtrons PX5 headunit. I would like to test the new app on my older MTCD RK3188 headunit. You can extract the apk with "App Backup Restore - Transfer" from the google play store: https://play.google.com/store/apps/details?id=mobi.infolife.appbackup&hl=en
Thank you!

Try using "ES File Explorer" to extract the Vehicle.apk. It is a system app so you may have to search for it under system apps in ES File Explorer. Here is a guide how to: http://thetechgears.com/backup-android-apps-apk-files-using-es-file-explorer/

Hi Marchnz,
I can't pull my hu out to take some internal pictures.. for the following reason:
1- no one especially a clever guy will avoid his head unit warranty by broken the warranty seal, especially for a brand new hu, to take some pictures!
2- is pain in the a.. to pull the hu out an Audi A4 car because the quadlock cables harness they are exactly behind the antenne of the hu, xtrons should put the antenna on the right site!
so man need to pull this quadlock cables harness as far as possible down and as fast as possible pushing / putting the hu in the dash because the quadlock cables harness come quickly back.. like a spring, spring back!
I hope you understanding my honesty reason.
Success :good:

Are you happy with your purchase so far?
Is the octa core faster? or feel smoother than de quad core?
What about the heat? I see the hu has an active cooling system, gotta keep it clean though, and as u said it may be tough to pull off the hu.

HIZPO Offering Quad Core A9 7" w/ Android 7.1

Thoughts? Thinking about ordering one.
I just returned a headunit from ATOTO because it worked like crap.
I like the prospect of 7.1 and offline maps already installed.
Quadcore vs Octacore I don't think makes a huge difference here.
Would love to know opinions.

I have a similar product to this with the product ID "B071LT7LC3" on Amazon. (I cannot post links yet) From the looks of things, my unit is likely the same hardware as yours, only with a different front panel and added DVD player. This is the information I read from the device:
MCU version: MTCD_XRC_V2.52_1
Build number: px3-userdebug 7.1.1 NMF26X eng.hct.20170527.145603 test-keys
Kernerl version: 3.0.101+ [email protected] #550
Model: px3 (800x480 O)
I sadly managed to brick mine by running an incompatible root method for Joying devices via Wireless ADB. I have not found a root method actually works on these units yet. If you are looking for an Android stereo that you can root, look elsewhere. I got a copy of the firmware from Hizpo, but not even that can fix the damage I did to it. It is with this warning I hope to prevent you making the same expensive mistake.
Note that you cannot use these units with a PC via USB, you must use Wireless ADB using an app. Use "126" to get into your factory settings and play with those, or "adbon" to enable debugging. You can also download a Development Options app to reach those settings, as they are hidden. The various methods of recoveries, including the one provided by the seller (Hold down the power button, turn on the power to the radio, release after 5 seconds and wait 30 to reach the recovery), did not seem to work for me either. It is possible I corrupted that too, but I am not sure.
I will happily share any other opinions I have about the unit if I ever manage to get it unbricked.

FYI - there are literally 1000s of different MTCD units by about 10 different manufacturers, they all share pretty much the same hardware and the software is interchangeable

But certainly not root methods and certain firmwares. Pick the wrong one and you can brick your device beyond restoration - to the point where the recovery does not work and no firmware update worked to fix it. I had to get a new unit.

Yes, all RK3188 MTCD units are the same inside, they use the same SoM and ROMs ARE compatible as long as you get the screen res and processor type correct and even if you get the screen res wrong its no big deal, it wont brick.
However if you flash the firmware from an MTCB unit, or from an entirely different, unrelated unit , its sounds like this is what you did.

I was looking at this, but when I noticed it said PX3 I decided to skip.. Doesn't make sense to not have the PX5 chip.
Now if there was a version with a PX5 on the new os Id be interest.

Sure the PX5 will be fast, but the PX3, especially with 2Gb of RAM is perfectly good.

If you decide to order, please update with your impressions. I too tried the ATOTO M4 garbage head unit, and it has almost encouraged me to give up on them entirely. If you find this one to be worthwhile, with it being at a similar price I might give it a shot.

No need for him to post impressions - its an MTCD unit and theres a whole forum about that you can read to see what theyre like :

No, not all units are MTCD, I ve heard a rumour that a company is working on MTCB/C N, even if that is untrue then you can still buy MTCB/C units.

Yeah, makes me laugh, the sellers must be stupid, why dont they update the KK ones to L ? they can sell them for more.

Anyway to tell if MTCB before buying?

After reading mixed reviews about these things, I want to be sure they can run a custom rom, before buying. Is there anyway to tell?
I have been looking at the 8 core 64gb memory, 4gb memory from Seicane for a Chrylser 300. This one on Alibaba.
https://www.aliexpress.com/item/400...earchweb0_0,searchweb201602_,searchweb201603_
Anyone know if this can run custom rom? or a way to find out?

You want an MTCD/E/P, MTCB units are long retired. Ask seller to tell you what the "MCU" is listed as -anything starting 'MTCD or MTCE or MTCP' is such a unit.

They're all flawed, [GS] MCU Type (Factory) may still be sold by reseller Xtrons and [HA] MCU/Factory Type sold by Dasaita/HotAudio appear to be the better of the bad.

Thanks, they dont make one for my car. Thanks though.
I seen on 300 forums, there was a unit that keeps being suggested Thread goes back to late 17, till about now and all have had good results and units still work. So hopefully they have the right MCU.
